Was that a typo above where you say " but I figure out how to do it" ?
Should it say "but I can't figure out how to do it" ?
An image map is really a poor way to try to get a nice cloudy sky.
I strongly urge you to instead take a look at this on line tutorial
about creating clouds using Pov-Ray :

It is true you cannot use interlaced gifs with Pov. You could onthe other
hand take it into an image processing program and save
it as a type 89 non-interlaced gif image and have no problems.
The basic syntax for using and scaling an image map is as follows:
plane{x,0
pigment{
image_map{gif "image.gif" interpolate 2}
translate -0.5
scale<360,280,1> // whatever size you need here to fill the screen
}
}
